Electroconvulsive therapy with S-ketamine anesthesia for catatonia in coexisting depression and dementia

  • Zsuzsa Litvan (a1), Martin Bauer (a1), Siegfried Kasper (a1) and Richard Frey (a1)


Information on efficacy and safety of electroconvulsive therapy in patients with dementia is sparse. The current case report describes a patient suffering from severe depression and dementia who received electroconvulsive therapy with S-ketamine anesthesia at our psychiatric intensive care unit for the treatment of her therapy-resistant catatonic stupor. The patient's condition improved remarkably through the treatment. By the end of 16 electroconvulsive therapy sessions, her catatonic symptoms remitted entirely, her affect was brighter and she performed markedly better at the cognitive testing.
